Description
A beautiful desk lamp using an RGB LED strip and an ESP8266 controller. No coding required!
Cost is $70 once you factor in what you'll use, more up front for the spools of filament. For parts I used, see the table and links below. I followed this youtube video by Core Electronics for the LED strip part. You can control it over WiFi via WLED, which is awesome. The strip is glued to the inner support pole, and I did some measuring with a string to get the angle and length exactly right.

| Bright White PLA Filament (1 Kg) | 0.153 | $29.99 | $4.59 |

I made it somewhat modular so you could make them taller or shorter. The outer pieces are printed in vase mode and just glued together.
I used a 0.8mm nozzle for the outer transparent parts for some additional speed and rigidity.
